Problems solved by technology

The problems that existing seedling raising substrates have: 1. The seedling raising time is long, the emergence rate is low, and there are defects such as short plant height and few leaves in the seedling stage, which seriously affects the output of tobacco seedlings and causes great harm to tobacco enterprises. Impact
2. Peat, a common substrate for tobacco seedling cultivation, is a non-renewable natural resource. Long-term use will inevitably cause serious ecological damage and exhaustion of natural resources, thereby limiting the development of tobacco seedling cultivation
[0003] At present, the utilization rate of wheat straw is low. In many areas, the straw is still piled up in the field and left to rot naturally or transported to the power plant for burning, which not only causes a waste of resources, but also pollutes water bodies and air

Abstract

The invention discloses a preparation method of a wheat straw type tobacco water-raised seedling substrate. The preparation method comprises the following steps: spraying water to a straw pile body firstly, wherein the mass ratio of the water to straw is (0.8-1.2) to 1; dissolving urea powder accounting for 1-2 percent of the total mass of the straw into water, and spraying the dissolved urea powder into the straw pile body; taking 0.5 billion cfu/g of mixed bacterial agent of aspergillus niger and bacillus licheniformis, uniformly spraying the mixed bacterial agent into the straw pile body, wherein the mixed bacterial agent accounts for 0.1-0.5 percent of the total mass of the straw; scattering bean cake powder accounting for 2-4 percent of the total mass of the straw into the straw pile body to be fermented, and turning the pile for 45-60 days every 3-6 days to obtain a wheat straw fermentation broth; and mixing the following components in parts by weight: 50-80 parts of the wheat straw fermentation broth, 5-15 parts of vermiculite, 3-12 parts of perlite, 15-25 parts of carbonized rice hulls and 10-20 parts of fly ash to obtain the wheat straw type tobacco water-raised seedling substrate. The preparation method is simple in step, available in raw materials and low in cost. The seedling substrate is short in seedling time, high in seedling emergence rate and good in growth vigor of tobacco seedlings in the seedling formation period.

Description

technical field [0001] The invention relates to a wheat straw type tobacco seedling-raising substrate and a preparation method thereof. Background technique [0002] In recent years, the promotion of artificial tobacco seedlings has increased rapidly. Artificial seedlings are not disturbed by the climate, with high yield and fast growth. The seedling substrate is the most critical substance in artificial seedlings. Ratio of seedling substrate has a great influence on the growth of tobacco seedlings. The problems that existing seedling raising substrates have: 1. The seedling raising time is long, the emergence rate is low, and there are defects such as short plant height and few leaves in the seedling stage, which seriously affects the output of tobacco seedlings and causes great harm to tobacco enterprises. Impact. 2. Peat, a common substrate for tobacco seedling cultivation, is a non-renewable natural resource. Long-term use will inevitably cause serious ecological damag...
